IMPROVEMENT IN coMerNINe- HARD RDBBER WITH JET AND OTHER' sUBsTANcEsTo l PRoDUcE USEFUL AND ORNAMENTAL ARTICLES.

- The Schedule referred to'in these Letters Patent and making part of the same.

` To whom 'it ma/y concern:

Be it known -th'at I, WILLIAM BYRON', of the city, county, and State of New York, have invented a new l and improved Method of Combining Hard Rubber with Jet or other Substances for Ornamentaland Useful Pur? poses; andi hereby declare the following to be a fiill,

and expense.

1t is also known that jet, while presenting aline appear-ance, and retaining its polish permanently, is yet l too brittle and frail to be used for ornamental or useful purposes by itself, and without the aid of othermaterial.

For instance, a'jet button, onstud, or pin, would be entirely too frail for practical use, and therefore-gwhen used in this connection, it is set in gold or other. metallic frame.

The object I have` in view vis to eiect such a union of the jet or other substance and the hard rubber, that while the jet shall form the upper part or exposed surface, the hard rubber, intimately united-with it,

shall form the body o f the article,l or-that part in which the strength isrequired. To this end,

My invention consists in uniting the hard rubber with thejet or other substance, such as glass, cameo, &c.,

capable of receivingand retaining a high degree of polisb, in the manner substantially as hereinafter described, andas shown in theY accompanying drawing, in which I have represented, in illustration 'of my invention, several modes of making a stud of combined jet and'hard rubber.

In Figure l, a is the jet or other substance to form the exposed surface of the article, cut awayon the underside, soas to form a recess with dovetailed sides. The backing of the jet,as welles the shank and lower button of 'the stud, isformed of hard rubber, b, which is turned, or cut, or otherwise formed in the shape required. 'lhe two are united by softening the head of the rubber by heat, and then pressing it, when suicientlyjsoft, against the jet, so astollall parts of the recess, after which the article can be trued, finished,

and polished in the usual manner. As the rubber is'- .v

thus dovetailved into the recess inthe jet, the union between the two 4is complete and permanent, and it is in fact difficult to determine the line of demarkation between them.

A second method, illustrated in Figures 3 and 4, is to press the rubber into the recessed jet, so that it will fill therecess only. In figs. 1 and 2, the upper half ofthe disk, or completed button, is composed of jet, and the lower of rubber; but in that now represented,

`both the face and sides'of the button are externally" jet, the bard rubber being only in the interior of the jet', and of course forming also the shank and lower butt-ou of the stud.v

A third method is represented in Figure 5, the jet being drilled with inclined holes, in which the rubber is pressed, forming also a backing, to which the rub- .b'er shank and lower buttouare held. Other means' for thus uniting the parts will readily sug gest themselves, but those already indicated will serve fully. to illustrate the nature of my invention. In each case it will be seen that the exposedsurface ofthe article is composed of the material which isfadapted to receivegand retain a high degree of polish, while that portion whichshould be of greater strength is composed .of hard rubber, which, although not capable of properly retaining, without care and labor, the finish required for the exposed surface, is, on account of its.

Istrength and toughness, admirably adapted to form the body of the article.

While describing, in illustration of my invention, the manuel' in which it may be applied to the manufacture of studs, I do not limit myself to this manufacture, but contemplate its application to any and all branches of the useful arts whereit may be made available; and, therefore,

What I claim, and desire to secure by Letters Patent is 1. The method `of combining hard rubber, or vnlcanite, with jet or other substances, substantially in the manner and for the purposes set forth.

2. As a new manufacture, jewelry composed of jet,

mounted iu or upon, or combined with hard rubber,

substantially as herein described.

v In testimony whereof, 1 have signed my name to this specicatiou, before two subscribing witnesses. WILLIAM BYRON. Witnesses:
